摘要：
Activation of the ammonia molecule and subsequent adsorption of the NH2 fragment on the surface of the NiO + Pd/TiO2 catalysts, in contrast to NiO + Pd/SiO2 catalysts, was demonstrated by IR spectroscopy. The decrease in the NiO + Pd/TiO2 Catalyst acidity was manifested in the higher catalyst stability in reductive amination of diethylene glycol to morpholine.
